Real-time Global Navigation Satellite Systems (GNSS) positioning are becoming more and more accessible and reliable due to the rapid growth of Continuously Operating Reference Station (CORS) networks around the world and a new form of positioning known as Network Real Time Kinematic (NRTK). As a result, the number of users and as well as the range of applications of GNSS has increased substantially. This growth has brought with it some interesting challenges one of which is to ensure that GNSS is performing at the required level of accuracy and precision. This has also placed an added responsibility to the suppliers of NRTK services to ensure that they can consistently satisfy the requirements of the users. At the moment there is no reliable system that can inform users as well as providers of NRTK services to the quality of positioning data. This research is concerned with developing and implementing a robust, independent quality control system that will inform users in real-time of the quality, dependability and fitness-for-purpose of NRTK positioning results. This paper will describe the current state of development of the system and will present some preliminary results from a kinematic railway survey.
